Abstract

PCT No. PCT/FI87/00034 Sec. 371 Date Oct. 16, 1987 Sec. 102(e) Date Oct. 16, 1987 PCT Filed Mar. 13, 1987 PCT Pub. No. WO87/05644 PCT Pub. Date Sep. 24, 1987.A floater dryer for drying a web-shaped (W), moving material, in particular a paper or cardboard web. The dryer comprises a plurality of radiation/air blowing units (10) which are provided on one side of the web (W) or on both sides (10A,10B). The units (10) have been shaped to be blow boxes having on their side facing the web (W) a contact-free carrier surface (21R,27) and into conjunction with which is blow, through a nozzle aperture (20a,20b) opening on the leading and/or trailing edge of the carrier surface, an air jet (Ful), or air jets (Fua,Fub). The jets will have a substantially large component parallel to said carrier surface. In conjunction with the radiation/air blowing units (10) are provided radiation elements (30) from which into the treatment interval (P1, P2, P-) is directed radiation (SO) through a window (27). The window at the same time serves as carrier surface for the air support of the web (W). The air flows (F3,F4) from the blow box are also conducted to serve as cooling air for the radiation elements (30) and for components in conjunction therewith. On the side opposite to the carrier surface (27,21R) of the radiation/air blowing units (10) may be provided a mirror arrangement (32,33) which returns radiation that has passed through the web (W), back to the web (W).
